BACKGROUND OF THE INVENTION

This invention relates to a novel promoter, a novel DNA construct containing the promoter and a Bt gene, and plants, especially corn plants, containing the novel DNA construct.

Bacillus thuringiensis (Bt) belongs to a large group of gram-positive, aerobic, endospore forming bacteria. During sporulation, these specific bacteria produce a parasporal inclusion body which is composed of insecticidally active crystalline protoxins, also referred to as δ-endotoxins.

These endotoxins are responsible for the toxicity of Bacillus thuringiensis to insects. The endotoxins of the various Bacillus thuringiensis strains are characterized by high specificity with respect to target organisms. With the introduction of genetic engineering it has become possible to create recombinant Bt strains which may contain a chosen array of insect toxin genes, thereby enhancing the degree of insecticidal activity against a particular insect pest.

The insecticidal crystal proteins from Bt have been classified based upon their spectrum of activity and sequence similarity (Hofte and Whiteley, Microbiol. Rev., 1989, 53:242-255 and Yamamoto and Powell, Advanced Engineered Pesticides, 1993, 3-42). Hofte and Whiteley published a classification scheme for the cry genes. Type I genes were considered active only against Lepidoptera species; Type II genes were active against Lepidoptera and Diptera species; Type III genes were active against Coleoptera species and Type IV genes included both 70- and 130-kDa crystal protein and were highly active against mosquito and blackfly larvae. However, since this original classification many novel cry genes have been cloned and sequenced demonstrating that the original system based on insect specificity required modification. A classification based on sequence homology along with new nomenclature based solely on amino acid identity has been proposed. (See Crickmore et al., Abstracts 28th Ann. Meeting Soc. Invert. Path. (1995), p14, Soc. Invert. Path., Bethesda Md.).

In this invention, the Cry proteins which are particularly effective against Lepidoptera species are preferred. These proteins are encoded by the following nonlimiting group of genes: cry1Aa, cry1ab, cry1Ac, cry1B, cry1C, cry1D, cry1E, cry1F, cry1G, cry2A, cry9C, cry5 and fusion proteins thereof. Among the cry genes, cry1Aa, cry1Ab, and cry1Ac show more than 80% amino acid identity and cry1Ab appears to be one of the most widely distributed cry genes. The Cry1Ab proteins are particularly effective against larvae of Lepidoptera (moths and butterflies).

The ingestion of these proteins, and in some cases the spores, by the target insect is a prerequisite for insecticidal activity. The proteins are solubilized in the alkaline conditions of the insect gut and proteolytically cleaved to form core fragments which are toxic to the insect. The core fragment specifically damages the cells of the midgut lining, affecting the osmotic balance. The cells swell and lyse, leading to eventual death of the insect.

A specific Lepidoptera insect, Ostrinia nubilalis (European corn borer (ECB)), causes significant yearly decrease in corn yield in North America. One study reveales that approximately 10% of the corn acres planted in the State of Illinois experienced a 9 to 15 percent annual yield loss, attributable solely to damage caused by the second generation of corn borer. Other important lepidopteran insect pests of corn include Diatraea grandiosella (Southwestern Corn Borer), Helicoverpa zea (Corn Earworm) and Spodoptera frugiperda (Fall Armyworm). The management practices of planting resistant or tolerant corn hybrids and treatment with chemical and microbial insecticides have not been satisfactory due to the low level of control provided by insecticidal treatments and the lack of hybrid lines resistant to second generation corn borers. Further tolerant and resistant hybrids often do not yield as well when infestation of ECBs are heavy. The use of corn genetically engineered to be resistant to specific corn insect pests has many advantages and these include a potential for substantial reduction in chemical insecticides and selective activity of the engineered endotoxin which will not disrupt the population of beneficial non-target insect and animals.

Toxic Bt genes from several subspecies of Bt have been cloned and recombinant clones have been found to be toxic to lepidopteran, dipteran and coleopteran insect larvae. However, in general, the expression of full length lepidopteran specific Bt genes has been less than satisfactory in transgenic plants (Vaeck et al, 1987 and Barton et al, 1987). It has been reported that the truncated gene from Bt kurstaki may lead to a higher frequency of insecticidal control. (U.S. Pat. No. 5,500,365). Modification of the existing coding sequence by inclusion of plant preferred codons including removal of ATTTA sequences and polyadenylation signals has increase expression of the toxin proteins in plants. (U.S. Pat. No. 5,500,365). In the present invention a truncated Bt kurstaki HD-1 gene has been used.

The instant invention additionally includes a second coding segment. The second coding segment comprises a DNA sequence encoding a selective marker for example, antibiotic or herbicide resistance including cat (chloramphenicol acetyl transferase), npt II (neomycin phosphototransferase II), PAT (phosphinothricin acetyl transferase), ALS (acetolactate synthetase), EPSPS (5-enolpyruvyl-shikimate-3-phosphate synthase), and bxn (bromoxynil-specific nitrilase). A preferred marker sequence is a DNA sequence encoding a selective marker for herbicide resistance and most particularly a protein having enzymatic activity capable of inactivating or neutralizing herbicidal inhibitors of glutamine synthetase. The non-selective herbicide known as glufosinate (BASTA® or LIBERTY ®) is an inhibitor of the enzyme glutamine synthetase. It has been found that naturally occurring genes or synthetic genes can encode the enzyme phosphinothricin acetyl transferase (PAT) responsible for the inactivation of the herbicide. Such genes have been isolated from Streptomyces. These genes including those that have been isolated or synthesized are also frequently referred to as bar genes. As used herein the terms “bar gene” and “pat gene” are used interchangeably. These genes have been cloned and modified for transformation and expression in plants (EPA 469 273 and U.S. Pat. No. 5,561,236). Through the incorporation of the pat gene, corn plants and their offspring can become resistant against phosphinothricin (glufosinate).

Another aspect of the invention includes a plant cell co-transformed with a first nucleic acid construct comprising, a CaMV 35S constitutive promoter which functions in plant cells operably linked to a maize alcohol dehydrogenase intron, a DNA sequence of a gene encoding a Cry1Ab protein toxin or a functionally related protein toxin, and a terminator functional in plants and a second nucleic acid construct comprising a CaMV 35S promoter which functions in plant cells operably linked to a maize alcohol dehydrogenase intron, a DNA sequence of a gene encoding for phosphinothricin acetyl transferase, and a terminator functional in plants wherein the first and second constructs are stably integrated in the plant genome.

The DNA construct of the invention preferably is an expression cassette functional in a plant comprising a promoter functional in plants, for example a CaMV 35S promoter, e.g., as disclosed in SEQ ID No. 1 or 5, preferably SEQ ID No. 1, operably linked to an intron which functions in monocots, for example a maize alcohol dehydrogenase intron, e.g., as disclosed in SEQ ID No. 2 or 6, preferably SEQ ID No. 2. This promoter/intron sequence is operably linked to a DNA sequence of interest, for example a gene encoding a Bt delta-δ-endotoxin, e.g., encoding the toxin domain of a Cry1Ab protein or a functionally related toxin protein, preferably modified for expression in plants, for example as depicted in SEQ ID No. 3, or a gene for a selectable marker, for example a gene for herbicide resistance, preferably glufosinate resistance, for example a Pat gene, e.g., as depicted in SEQ ID No. 7. The gene of interest is suitably linked to a terminator functional in plants, e.g. a Nos terminator, for example as disclosed in SEQ ID No. 4 or 8, preferably SEQ ID No. 4, to form an expression cassette functional in a plant. Especially preferred embodiments of the Bt expression cassette comprise SEQ ID Nos. 1, 2, 3 and 4 in operable sequence, e.g., as in the Btk cassette described below. Especially preferred embodiments of a Pat expression cassette comprise SEQ ID Nos. 5, 6, 7, and 8 in operable sequence. In an especially preferred embodiment, a Bt expression cassette as described herein is linked on the same DNA with a Pat expression cassette as described herein, e.g., a plasmid comprising cassettes formed by SEQ ID Nos. 1-4 and 5-8 wherein the two cassettes are transcribed in the same direction, e.g., as in plasmid pZO1502.

The use of such expression cassettes in a method of transforming plants, e.g., maize plants, for example a method or biolistic or protoplast transformation of maize plants, especially protoplast transformation as described in the examples herein is also provided, as are plants stably transformed with expression cassettes as described, particularly maize plants, e.g., field corn, sweet corn, white corn, silage corn and popcorn, and seed thereof. Particularly preferred are maize plants and seed thereof descended from the Bt11 transformation event described in Example 2, for example

Maize containing the Btk construct described within a 15 cM region of chromosome 8, near position 117, in the approximate position of public probe UMC30a, in the interval flanked by two markers: Z1B3 and UMC150a, preferably

(i) elite inbred sweet corn lines R327H, R372H, R412H, R583H and R660H,

(ii) elite inbred field corn lines 2043Bt, 2044Bt, 2070Bt, 2100Bt, 2114Bt, 2123Bt, 2227Bt, 2184Bt, 2124Bt, and 2221Bt, and

(iii) maize inbred varieties descended from the same transgenic event as these lines which contain and express the same transgenic construct, including seed thereof.

When particular inbred varieties are identified herein, it is understood that the named varieties include varieties which have the same genotypic and phenotypic characteristics as the identified varieties, i.e., are derived from a common inbred source, even if differently named. The invention also provides hybrid maize seed produced by crossing plants of an inbred corn line as described above with plants of having a different genotype, and hybrid corn plants produced by growing such hybrid maize seed. Also provided is a method of producing hybrid maize seeds comprising the following steps:

A. planting in pollinating proximity seeds of a first inbred maize line as described herein and seeds of a second inbred line having a different genotype;

B. cultivating maize plants resulting from said planting until time of flowering;

C. emasculating said flowers of plants of one of the maize inbred lines;

D. allowing pollination of the other inbred line to occur, and

E. harvesting the hybrid seeds produced thereby.

Also provided are hybrid seeds produced by this method, F1 hybrid plants produced by growing such seeds, and parts of such F1 hybrid plants, including seeds thereof.

Seeds of the plants described herein (e.g., of maize plants, e.g., Bt11 maize plants, for example inbred or hybrid seeds as described above) for planting purposes is preferably containerized, e.g., placed in a bag or other container for ease of handling and transport and is preferably coated, e.g., with protective agents, e.g., safening or pesticidal agents, in particular antifungal agents and/or insecticidal agents. One particular embodiment of this invention is isolated inbred seed of the plants described herein, e.g. substantially free from hybrid seed or seed of other inbred seed, e.g., a seed lot or unit of inbred seed which is at least 95% homogeneous, e.g., isolated seed of any of the maize inbreds described in example 8 or 9 hereof.

Also provided herein, for the first time, are Bt maize varieties other than Bt field corn, particularly Bt sweet corn. Although Bt field corn has been disclosed, it was not previously determined experimentally whether or how a Bt delta δ-endotoxin would interact with traits associated with sweet corn, which is harvested at an earlier maturity (before it is dry), for a different purpose (usually fresh produce, canning or freezing, for human consumption) and has been bred therefore to be qualitatively and quantitatively different from field corn in a number of respects. Therefore, in one embodiment, the invention comprises a sweet corn comprising in its genome an expression cassette comprising a coding region for a Bt delta-δ-endotoxin or functional fragment or derivative thereof, under control of a promoter operable in maize, e.g., an expression cassette as described herein. The sweet corn of the invention includes sweet or supersweet maize having a higher sugar to starch ratio than field corn (e.g., yellow dent corn) due to a reduced capacity to convert sugar into starch, typically characterized by a sugary (su, e.g., su1) allele in the case of sweet corn, and/or shrunken allele (sh, e.g., sh2) or brittle allele (bt, e.g., bt2, not to be confused with the gene for an endoxin from Bacillus thuringiensis, described elsewhere herein) in the case of supersweet corn, especially maize containing the sul or sh2 alleles.

Bt maize of the invention, e.g., Bt11 maize, is found to be particularly suited for the preparation of food materials (e.g., for human or animal consumption, for example sweet corn for for packaging or fresh use as a human food, or grain or silage made from field corn) containing reduced levels of fungal toxins, e.g., aflatoxins. While the mechanism is not entirely understood, in grain and silage made from Bt11 maize, the level of aflatoxin is believed to be lower, possibly because the reduction in insect damage reduces the level of opportunistic fungal infection in the growing plant. Accordingly, food materials made from Bt maize of the invention, particularly Bt11 maize, for example grain and silage having reduced levels of fungal toxins, particualrly aflatoxins, and the use of the Bt maize of the invention in a method of preparing a foodstuff, especially grain or silage, with reduced levels of fungal toxins, e.g., aflatoxins, is also provided.

DETAILED DESCRIPTION OF THE INVENTION

A promoter is defined as a nucleotide sequence at the 5′ end of a structural gene which directs the initiation of transcription. The structural gene is placed under regulatory control of the promoter. Various promoters which are active in plant cells are known and described in the art. These include Cauliflower Mosaic Virus (CaMV) 19S and 35S; nopaline synthase (NOS); mannopine synthase (MAS); actin; ubiquitin; ZRP; chlorophyll AB binding protein (CAB); ribulose bisphosphate carboxylase (RUBISCO); heat shock Brassica promoter (HSP 80); and octopine synthase (OSC). The particular promoter used in the present invention should be capable of causing sufficient expression to result in production of an effective amount of protein. The promoter used in the invention may be modified to affect control characteristics and further may be a composite of segments derived from more than one source, naturally occurring or synthetic. The preferred promoters are CaMV promoters and particularly CaMV 35S. The term “CaMV 35S” includes variations of the promoter wherein the promoter may be truncated or altered to include enhancer sequences, to increase gene expression level, and composite or chimeric promoters, wherein portions of another promoter may be ligated onto the CaMV 35S. A preferred embodiment includes the 5′ untranslated region of the native 35S transcript, and more particularly wherein the untranslated region includes about 100 to 150 nucleotides. Additionally while 35S promoters are fairly homologous, any 35 S promoter in a preferred embodiment would include the untranslated region of the native 35S transcript. Particularly preferred 35S promoters are described in SEQ ID NO. 1 and SEQ ID NO. 5. The promoter as described in SEQ ID NO. 1 as part of the claimed construct may have particular advantage in that the construct may be expressed in pollen tissue.

An intron is a transcribed nucleotide sequence that is removed from the RNA transcript in the nucleus and is not found in the mature mRNA. Such sequences are well known in the art, and monocot introns include but are not limited to sucrose synthetase (SS); glutathione transferase; actin; and maize alcohol dehydrogenase introns. An exon is part of a gene that is transcribed into a mRNA and includes non-coding leader and/or trailer sequences. An exon may code for a specific domain of a protein. Having native exon sequences around an intron may improve the introns splicing activity or the ability of the nuclear splicesomal system to properly recognize and remove the intron. According to the invention, a preferred embodiment includes the native exon in the first cassette and more particularly 50 or more nucleotide bases of the native exon on each side of the intron is preferred.

A gene refers to the entire DNA sequence involved in the synthesis of a protein. The gene includes not only the structural or coding portion of the sequence but also contains a promoter region, the 3′ end and poly(A) sequences, introns and associated enhancers or regulatory sequences.

A structural heterologous gene is that part of a DNA segment which encodes a protein, polypeptide or a portion thereof, and one which is not, normally found in the cell or in the cellular location where it is introduced. The DNA sequence of a structural heterologous gene of the present invention include any DNA sequence encoding a crystal toxin insecticidal protein. The preferred toxins include but are not limited to Cry1Aa, Cry1Ab, Cry1Ac, Cry1B, Cry1C, Cry1D, Cry1E, Cry1F, Cry1G, Cry2A, Cry2B, Cry3A, Cry3B, Cry3C, Cry4A, Cry4B, Cry4C, Cry4D, Cry5A, Cry9C, CytA and any fusion protein or truncated gene that encodes one or more of the abovementioned toxins or a mixture thereof. Particularly preferred toxins include Cry1Aa, Cry1Ab, Cry1Ac, Cry1C, Cry2A, Cry3C, Cry1E, Cry5A, Cry9C and any mixture or fusion protein thereof. In the present specification, the term fusion protein is used interchangeably with the terms fusion toxin and hybrid protein and is a protein consisting of all or part of an amino acid sequence (known as a domain) of two or more proteins, and is formed by fusing the protein encoding genes. An example of a DNA sequence useful in the cassette of this invention is a DNA sequence encoding a fusion toxin wherein the toxin is Cry1Ab/Cry1C and Cry1E/Cry1C. The domains comprising the fusion protein may be derived from either naturally occurring or synthetic sources.

Many cry1Ab genes have been cloned and their nucleotide sequences determined. A holotype gene sequence of cry1Ab has accession number M13898 (The GenBank v. 70/EMBL v.29). A number of studies reveal that the amino terminal end of the Cry1A protein is responsible for the insecticidal activity. This region depends on the particular protein but in general include a truncated gene that encodes from about amino acid 25 to amino acid 610 of the protein.

In the present invention, a preferred cry1Ab gene includes a synthetic gene encoding the toxin domain of the protein produced by the Bt kurstaki (k) HD-1 gene wherein the G+C content of the Btk gene is increased and the polyadenylation sites and ATTTA regions are decreased. U.S. Pat. No. 5,500,365, which is hereby incorporated in its entirety discloses a synthetic Btk HD-1 and HD-73 gene, and truncated HD-1 and HD-73 genes. A particularly preferred cry1Ab gene of this invention is the sequence as described in SEQ ID NO. 3.

Other preferred genes include those that are functionally equivalent to cry1Ab. These genes include all cry1Ab, cry1Aa, cry1Ac and variants thereof wherein the expressed protein toxin is active against one or more major maize Lepidoptera insect pests. The insect pests include the aforementioned European corn borer, Southwestern corn borer, Fall armyworm, and Corn earworm. The second structural gene that is part of the invention includes a DNA sequence encoding a selective marker for example, antibiotic or herbicide resistance including cat (chloramphenicol acetyl transferase), npt II (neomycin phosphototransferase II), PAT (phosphinothricin acetyltransferase), ALS (acetolactate synthetase), EPSPS (5-enolpyruvyl-shikimate-3-phosphate synthase), and bxn (bromoxynil-specific nitrilase). A preferred marker sequence is a DNA sequence encoding a selective marker for herbicide resistance and most particuarly a protein having enzymatic activity capable of inactivating or neutralizing herbicidal inhibitors of glutamine synthetase. The non-selective herbicide known as glufosinate (BASTA® or LIBERTY ®) is an inhibitor of the enzyme glutamine synthetase. It has been found that naturally occurring genes or synthetic genes can encode the enzyme phosphinothricin acetyl transferase (PAT) responsible for the inactivation of the herbicide. Such genes have been isolated from Streptomyces. Specific species include Streptomyces hygroscopicus (Thompson C. J. et al., EMBO J., vol. 6:2519-2523 (1987)), Streptomyces coelicolor (Bedford et al, Gene 104: 39-45 (1991)) and Streptomyces viridochromogenes (Wohlleben et al. Gene 80:25-57 (1988)). These genes including those that have been isolated or synthesized are also frequently referred to as bar genes. As used herein the terms “bar gene” and “pat gene” are used interchangeably. These genes have been cloned and modified for transformation and expression in plants (EPA 469 273 and U.S. Pat. No. 5,561,236). Through the incorporation of the pat gene, corn plants and their offspring can become resistant against phosphinothricin (glufosinate). A preferred coding segment of a bar gene of the present invention is the sequence described in SEQ ID NO. 7.

The structural gene of this invention may include one or more modifications in either the coding region or in the untranslated region which would not substantially effect the biological activity or the chemical structure of the expression product, the rate of expression or the manner of expression. These modifications include but are not limited to insertions, deletions, and substitutions of one or more nucleotides, and mutations. The term homology as used herein refers to identity or near identity of nucleotide or amino acid sequences. The extent of homology is often measured in terms of percentage of identity between the sequences being compared. It is understood in the art that modification can occur in genes and that nucleotide mismatches and minor nucleotide modifications can be tolerated and considered insignificant if the changes do not alter functionality of the final product. As in well known in the art the various cry1A genes have very similar identity and reference in made to the article by Yamamoto and Powell, Advanced Engineered Pesticides, 1993, 3-42 which includes a dendrogram table showing sequence homology among full length crystal proteins obtained from the GenBank data base for a full length comparision.

Termination sequences are sequences at the end of a transcription unit that signals termination of transcription. Terminators are 3′ non-translated DNA sequences that contain a polyadenylated signal. Examples of terminators are known and described in the literature. These include but are not limited to nopline synthase terminator (NOS); the 35S terminator of CaMV and the zein terminator.

Other elements may be introduced into the construct for examples matrix attachments region elements (MAR). These elements can be positioned around an expressible gene of interest to effect an increase in overall expression of the gene and to diminish position dependent effects upon incorporation into the plant genome.

Transformation means the stable integration of a DNA segment carrying the structural heterologous gene into the genome of a plant that did not previously contain that gene. Co-transformation is transformation with two or more DNA molecules. Frequently one segment contains a selectable gene generally one for antibiotic or herbicide resistance.

As used herein the term plant tissue is used in a wide sense and refers to differentiated and undifferentiated plant tissue including but not limited to, protoplasts, shoots, leaves, roots, pollen, seeds, callus tissue, embryos, and plant cells (including those growing or solidified medium or in suspension.

The DNA construct of this invention may be introduced into a plant tissue by any number of art recognized ways. These included, but are not limited to, direct transfer of DNA into whole cells, tissue or protoplasts, optionally assisted by chemical or physical agents to increase cell permeability to DNA, e.g. treatment with polyethylene glycol, dextran sulfate, electroporation and ballistic implantation of DNA coated particles.

EXAMPLE 1: Plasmid construction

A. Plasmid pZO1502 construction: The plasmid pZO1502 can be considered to consist of three basic regions; the base plasmid vector, an expression cassette for the Btk gene, and an expression cassette for the pat gene. For convenience, the various parts were constructed separately and then combined into the final plasmid. In order to assemble the desired elements for the Btk and pat gene expression cassettes, the restriction sites used to generate the desired elements sometimes required modification. The following example demonstrates the procedure used to produce the pZO1502 plasmid. One skilled in the art could devise alternate ways to construct the final transformation plasmid.

B. Base Plasmid Vector: The base vector, pUC18 (GenBank accession L08752, Norrander, J. M., et al., 1983. Gene 26:101-106), was modified by replacing the EcoO 109 I restriction site with a Bgl II linker (digestion with EcoO 109 I, fill in with T4 polymerase, and addition of a Bgl II linker). This base vector was further modified to replace the BspH I sites at 1526 and 2534 with Not I restriction sites (vector cut with BspH I, filled in, and replaced with Stu I linkers; the Stu I site was then cut and Not I linkers added). The addition of the Not I restriction sites provided a convenient way to produce a linear DNA fragment containing the two desired gene cassettes (Btk and pat) separated from the ampicillin gene sequence (required for plasmid production in E. coli). This linearization also significantly increased protoplast transformation frequency. The final base vector was named pZO997B (FIG. 2).

C. Btk gene expression cassette: The Dde I to Dde I fragment of the 35S promoter from cauliflower mosaic virus (strain CM1841, GenBank accession #V00140, Gardner, R. C., et al., 1981. Nucleic Acids Res. 9:2871-2888) (SEQ ID NO. 1) was converted to Sac I by addition of linkers and cloned into the Sac I site of the polylinker region of a pUC19 based vector. The sixth intron from maize Adh1-1S gene (GenBank accession X04049, Dennis, E. S., et al., 1984. Nucleic Acid Res. 12:3983-4000) was isolated as a Pst I to Hpa II fragment, converted with BamH I linkers (SEQ. ID NO. 2), and cloned into the BamH I poly linker site 3′ to the 35S promoter. The 3′ terminator from Nopaline synthetase, NOS, (GenBank accession V00087, Bevan, M., et al., 1983. Nucleic Acids Res. 11:369-385) (SEQ. ID NO 4) was isolated as ˜250 bp fragment with Pst I and Bgl II. The Bgl II site was polished With T4 polymerase, a Hind III linker added, and the fragment inserted behind a gus gene construct using the Pst I and Hind III sites. The gus gene was cloned into the Sal I to Pst I site of the polylinker. The gus construct utilized a synthetic linker (Sal I to Nco I, which provides for an A nucleotide at the −3 position from the translation start ATG: GTCGACCATGG) (SEQ ID NO. 9). The Pst I site was then trimmed, a Bcl I linker added, and the gus gene sequence replaced with a synthetic gene encoding a cry1Ab toxin (SEQ. ID NO. 3) as a Nco I to Bgl II insert to produce the vector pZO960 (FIG. 1)

D. Pat gene expression cassette: Although composed of similar elements, the pat expression cassette was derived from a different series of cloning steps. The 35S promoter (SEQ ID NO. 5) was obtained as a Hinc II to Dde I fragment from the cauliflower mosaic virus (strain CABB-S, GenBank accession #V00141, Franck, A., et al., 1980. Cell 21: 285-294) and converted to BamH I—Xba I with linkers. The second intron sequence from maize Adh1-1S (GenBank accession X04049, Dennis, E. S., et al., 1984. Nucleic Acid Res. 12:3983-4000) (SEQ ID NO. 6) was isolated as a Xho II to Xho II fragment and cloned into the BamH I site of pUC12, converting the Xho II sites to BamH I. As a BamH I fragment it was cloned into the Bgl II site of a synthetic polylinker (Asu II, Bgl II, and Xho I). The Asu II site was then filled in and ligated to the (filled in) Xba I site of the 35S promoter fragment. The synthetic pat gene sequence was subcloned from plasmid pOAC/Ac (obtained from Dr. Peter Eckes, Massachusetts General Hospital, Boston Mass.) (SEQ ID NO. 7) as a Sal I to Pst I fragment and combined with the 35S/Adhivs2 promoter (Xho I) and the 3′ NOS terminator sequence Pst I to Bgl II (GenBank accession V00087, Bevan, M., et al., 1983. Nucleic Acids Res. 11:369-385) (SEQ ID NO. 8). These pieces were all combined with the pZO997B base vector to produce the pat expression vector pZO1500 (FIG. 3).

As the final construction step, the Btk expression cassette was subcloned from pZO960 as an EcoR I-Hind III fragment and inserted into the EcoR I-Hind III polylinker site of pZO1500 to produce the final vector, pZO1502 (FIG. 4). The amp (beta-lactamase) gene was removed prior to plant transformation by digestion with NotI. pZO1502 has been deposited with the American Type Culture Collection (ATCC), 12301 Parklawn Drive, Rockville, Md. 20852-1776 USA pursuant to the Budapest Treaty prior to the filing of this application and accorded accession number 20982 on Mar. 13, 1998 , and the complete sequence of this plasmid is disclosed in SEQ. ID No. 9.

EXAMPLE 2: Protoplast transformation, selection of transformed corn cells and regeneration

The initial parental transformation of the corn line to be planted was accomplished through insertion of a DNA fragment from plasmid pZO1502, containing the two cassettes of Btk and the pat gene, into the genome of a proprietary corn cell line owned by Hoerchst AG (Frankfurt Germany). The transformation was performed using a protoplast transformation and regeneration system as described in detail in European Patent Application Publication Number 0 465 875 A, published Jan. 15, 1992 and European Patent Application Publication Number 0 469 273 A, published Feb. 5, 1992 and Theor. Appl. Gent. 80:721-726 (1990)). The contents of which are hereby incorporated by reference.

After some weeks on selective media putative transformant clumps of cells were observed and transformed protoplasts were selected in vitro with a glufosinate-ammonium herbicide. Sixteen leaf producing genetically transformed corn lines were obtained from protoplasts treated with the gene expression cassette from pZO1502. One of these lines was designated as transformant number 11. This transformant was grown to maturity.

The Bt-11 R0 transformed plants were pollinated with nontransformed Northrup King elite inbred male parents and R₁ seed was collected. Descendants of the initial crossing have been successively backcrossed and test crossed to establish and evaluate corn lines carrying the Btk gene. Such lines are described more fully in the Examples 8 and 9 below and have been deposited with the ATCC pursuant to the Budapest Treaty.

EXAMPLE 3: Stable Transformation

Expression of the Btk gene was tested by transforming the Bt gene vector pZO960 into BMS (Black Mexican Sweet) corn cells. Protoplasts were isolated from a suspension culture BMS cell line and electroporated to induce DNA uptake essentially as described in Sinibaldi, R. M. and Mettler, I. J., 1992, In: Progress in Nucleic Acid Research and Molecular Biology (W. E. Cohn and K. Moldave, eds.) Academic Press, San Diego, vol. 42:229-259. Cells which had stably incorporated DNA were selected by co-transformation with a plasmid containing a kanamycin resistance selectable gene. A number of independent transgenic events were selected by the expression of the antibiotic resistance to kanamycin. Approximately 1 gram of each transgenic line was then used to test for biological activity against neonate larvae of Manducca sexta. Control, non-transformed, BMS callus tissue supported normal growth of the larvae throughtout the test period. Transgenic callus lines were then rated for the degree of growth inhibition. As shown in Table 1, out of 33 BMS lines co-transformed with pZO960, 6 lines were positive for insecticidal activity showing complete growth inhibition and 100% mortality within 2 or three days. Quantitative Elisa assays showed that the transgenic tissues produced an average of 3.1 ng of Bt protein per mg of total extracted protein.

EXAMPLE 4: Insertion Site of Bt11 Transgenic Event

The original genetic stock into which the Btk sequence was transformed was designated HE89. The Ro plants were used as the female parent for initial crosses to two, elite Northrup King proprietary inbred lines for which Btk-conversion was sought. Multiple backcrosses were conducted into many additional inbred lines with individuals selected that contained the insertion sequence but were, otherwise, as similar to the elite recurrent parents as possible. Four or more backcrosses and selfing to homozygosity were used in the conversion process. Finished conversion stocks were evaluated with a series of 50 or 60 RFLP probes selected to be well distributed throughout the genome. Genotypes of the Btk converted inbreds were compared to those of their recurrent parent isolines. They were generally identical or nearly identical for all genetic markers, except for three probes on a small segment of the long arm of chromosome 8. All conversion stocks differ from the genotype of the transformed stock, HE89, for this segment, thus differing from the recurrent parents. There were no other genomic regions with consistent differences between Btk-conversions and their recurrent parents. These three probes exist within 10 centiMorgans(cM) of one another at the approximate position of the public probe UMC30a, which has been placed at map position 117 in the 1995 map of RFLP probe positions distributed by the University of Missouri at Columbia.

A series of 95 backcross progeny were further characterized with numerous probes in the region of chromosome 8 identified above. The size of the “donor” DNA segment varied among these progeny. However, five of the progeny failed to contain the donor alles at the flanking markers: Z1B3 and UMC150a, despite presence of the Btk sequence. These two probes are approximately 15 cM apart on chromosome 8. Thus, the insertion site is within a 15 cM region on the long arm of chromosome 8, near position 117, and in the interval flanked by two markers: Z1B3 and UMC150a

Southern Analysis of the Transgenic Event

The Bt11 transgenic seeds backcrossed into inbred line HAF031 (deposited with ATCC pursuant to the Budapest Treaty on Apr. 19, 1999 under designation 2044Bt and assigned accession number 203943) were sown in the greenhouse and sprayed with BASTA herbicide at the four leaf stage. Resistant plants and control, untransformed, HAF031 inbred plants were then used for DNA extraction and Southern blot analysis (T. Maniatis, E. F. Fritsch and J. Sambrook, 1982, Molecular Cloning A Laboratory Manual, Cold Spring Harbor Laboratory) The genomic DNA samples were digested with following restriction enzymes and probed with labeled DNA for Btk and PAT gene sequences. The first enzyme combination utilized 2 restriction sites present on the plasmid DNA. The next two enzymes bad only one known location and would be expected to cut the genomic DNA at a distant site in the plant DNA. The actual size of any observed fragment depends on the insertion event. The number of bands can be used to estimate insertion copy number—each gene copy would produce a unique band on the Southern blot.

The results of a Southern blot are summarized in Table 2 These data show that the Bt 11 transgenic lines are derived from a single insertion event containing one gene copy of the Bt and pat gene sequences.

EXAMPLE 5: Enzymatic Activity of PAT in the Bt Transformed Lines

Fresh tissue samples (3-50 mg) were ground on ice in ˜5 volumes of extraction buffer (100 mM Tris-HCL, pH 7.5), 3 mg/ml dithiothreitol and 0.3 mg/ml bovine serum albumin (BAS fraction V). The homogenate was centrifuged to clarity (12,000×g for 5 min). Approximately 2 μl of extract was added to the reaction mixture containing the extraction buffer plus 125 μM acetyl CoA and 250 μM phosphinothricin. The enzymatic reaction was allowed to proceed for 1 hour at 37° C. The reaction mix was then spotted onto TLC silica gel plates (Baker Si250-PA (19C)). The plate was chromatographed for 2-3 hours with isopropanol:NH40H (3:2), air dried and vacuum dried in an oven at 80° C. The plates were then exposed to X-ray film for 1-4 days. The results of a typical assay confirm the presence and enzymatic activity of the PAT protein in the Bt lines.

EXAMPLE 6: Inheritance and Gene Stability

The segregation of the Btk gene and the PAT gene were followed in multiple generations. Eight F1 corn plants identified as containing the Btk and PAT genes were selfed to produce a S1 population. The S1 population was screened for resistance to ECB and Ignite® herbicide. All plants were either resistant to ECB and Ignite or susceptible to both. The segregation ratios were consistent with an expected ratio of 3:1 for a single dominant locus.

EXAMPLE 7: Bt-11 maize versus European Corn Borer Field Trials

Trials were conducted using a randomized complete block design. Two replicates were planted at three locations across three states in two-row plots. Hybrids were grouped according to relative maturity and planted at appropriate sites based on maturity. Southern trials contained six Btk hybrids and four non-Btk control hybrids. The northern trials consisted of eight Btk hybrids and two non-Btk hybrids. Plants were artificially infected as they approached the V6 stage of growth. Approximatety fifty larvae were appplied to ten plants in the first row of each plot every three to four days over a two and one-half week period. By the end of the first generation infesting, each plant had been infected with at least 200 neonate larvae. Just prior to tassel emeregnce, 1-9 leaf damage ratings were assigned to each of the ten plants per plot. The rating scale of Gurthie, W. D., et al. (1960, “Leaf and Sheath Feeding Resistance to the European Corn Borer in Eight Inbred Lines of Dent Corn”, Ohio Ag. Exp, Sta. Res. Bull. 860) was used, wherein 1=no damage or few pinholes, 2=small holes on a few leaves, 3=shot-holes on serval leaves, 4=irregular shaped holes on a few leaves, and 9=several leaves with many emerging elongated lesions.

As plants began to shed pollen, second generation ECB infestation began. The first ten plants of the first row of each plot were infected with 40-50 larvae every three to four days over a two and one-half week period. Eventually every plant had been infected with approximately 200 more larvae. After approximately 45 to 50 days, plants were dissected from top to the ground and the total length of tunnels created by ECB feeding was estimated and converted to centimeters for reporting. Analysis of Variance and Least Significant Difference mean separation were used to analyze the results.

Average leaf feeding damage scores were approximately 3.9 on non-Btk hybrids and 1.1 for Btk hybrids wherein 1 on the scale of 1 to 9 represents no damage. Average stalk damage represented as centimeters tunneled per plant, was approximately 4.9 cm in the non-Btk control hybrids. The Btk hybrids displayed only approximately 0.2 cm of tunneling per plant. In all cases, the difference between Btk hybrids and non-Btk hybrids was significant at a P-value of less than 0.01 based on AVOVA and LSD mean separation. Field tests conducted to determined the resistance of Btk hybrids and non-Btk hybrids for Southwestern Corn Borer and Fall Armyworm also indicated that Btk hybrids showed excellent potential for assisting in the control of these insect pests.

EXAMPLE 8: Bt11 Sweet Corn

Inbred backcrossing of Bt 11 event material as described in Example 4 into Novartis (Rogers) elite inbred sweet corn lines was carried out to obtain Bt 11 inbred sweet corn lines, including inbreds R327H ATCC Accession No: 209673, deposited Mar. 11, 1998, R372H ATCC Accession No: 209674, deposited Mar. 11, 1998, R412H ATCC Accession No. 209675, deposited Mar. 11, 1998, R583H ATCC Accession No: 209671, deposited Mar. 11, 1998 and R660H ATCC Accession No: 209672, deposited Mar. 11, 1998 . These inbreds and their F1 hybrid progeny all contain the Btk insert as described above at the location described above and exhibit insect resistance and herbicide resistance as for the other lines descended from the Bt11 event. For example, 2500 seeds of each of these lines were deposited with ATCC prior to the filing of this application pursuant to the Budapest Treaty and accorded accession numbers as follows: R327H: , R372H: , R412H: , R583H: and R660H: . These lines were evaluated at Nampa, Idaho and Stanton, Minn. during the summer and fall of 1997, and characterized in relation to a standard reference inbred (Iowa5125, from North Central Region Plant Introduction Center, Ames, Iowa) having similar background and maturity, as depicted on the following table.

EXAMPLE 9: Bt11 Field Corn

Inbred backcrossing of Bt11 event material as described in Example 4 into Novartis (Rogers) elite inbred field corn lines was carried out to obtain Bt 11 inbred field corn lines, for example Yellow Dent inbred lines 2044Bt, 2070Bt, 2100Bt, 2114Bt, 2123Bt, 2227Bt, 2184Bt, 2124Bt, and 2221Bt. These inbreds and their hybrid progeny all contain the Btk insert as described above at the location described above and exhibit insect resistance and herbicide resistance as for the other plants descended from the Bt11 event. 2500 seeds of each of the following lines were deposited with ATCC pursuant to the Budapest Treaty on Apr. 19, 1999 and accorded deposit numbers as follows: 2044Bt: ATCC 203943, 2070Bt: ATCC 203941, 2227Bt: ATCC 203942, 2184Bt: ATCC 203944, and 2221Bt: Bt11 inbreds were also made by marker assisted inbred conversion of the following lines, NP948 (ATCC 209406), NP2017 (ATCC 209543), NP904 (ATCC 209458), NP2010 (ATCC), all deposited with ATCC pursuant to the Budapest Treaty to obtain 2100Bt, 2114Bt, 2123Bt and 2124Bt respectively.

Hybrids from Bt11 inbred conversions were evaluated extensively against hybrids from isogenic, non-transgenic parents in a number of field trials. In general, there was a significant yield advantage to the BT11 version. There was no attempt to control natural infestations of European Corn Borers in these trial locations. Grain moisture at harvest is sometimes slightly higher in the BT11 version. This can often be attributed to the improved plant health, due to reduced stalk rot. In some cases, grain test weight is higher in the BT11 version, which can also reduce the rate of grain dry down. Stalk lodging is typically lower in the BT11 versions. Push test and Late season intactness are also typically better in BT11 versions. In some cases, stay green is better. Plant and ear height are sometimes slightly higher in the BT 11 version. For other traits, no consistent detrimental changes in performance have been observed.

2124Bt, 2221Bt, and 2070Bt are southern (late) maturities, whereas 2044Bt, 2100Bt, 2114Bt, 2227Bt, 2184Bt, and 2123Bt are northern (early) maturities. These inbred Bt lines have the following general characterization:

2044Bt—dark-reddish purple silk, slight pale green color, very slightly faded chlorotic stripes in leaves, medium tall, medium ear-placement, purple tip to glume

2100Bt—green-yellow silk, medium-short plant height, medium low ear placement, green with purple glume, light green overall appearance

2114Bt—dark reddish purple silk, small tassel, slight crook in stalk nodes, slight pale green color, medium tall, medium ear placement, higher yielding than 2044Bt

2227Bt—very thin loose husk at harvest, root lodges, medium plant height, medium ear placement

2184Bt—medium plant height, medium ear placement, very light pollen shedder, green yellow silk color, pale purple anther

2123Bt—green with purple glumes, purple anther, green yellow silk, medium plant height
